highly integrated, USB microcontroller. By integrating the USB transceiver, Serial Interface Engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip, Cypress has created a very cost effective solution that provides superior time-to-market advantages. FX1 does not support the low speed signaling mode of 1.5 Mbps or the high speed mode of 480 Mbps. 8051 Microprocessor The 8051 microprocessor embedded in the FX1 family has 256 bytes of register RAM, an expanded interrupt system, three timer/counters, and two USARTs. The EZ-USB FX1 is more economical, because it incorporates the USB transceiver and provides a smaller footprint solution than the USB SIE or external transceiver implementations. With EZ-USB FX1, the Cypress Smart SIE handles most of the USB protocol in hardware, freeing the embedded microcontroller for application specific functions and decreasing the development time to ensure USB compatibility. 8051 Clock Frequency The General Programmable Interface (GPIF) and Master/Slave Endpoint FIFO (8 or 16-bit data bus) provide an easy and glueless interface to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, and most DSP/processors. Four Pb-free packages are defined for the family: 56-pin SSOP, 56-pin QFN, 100-pin TQFP, and 128-pin TQFP. Applications ■ DSL modems ■ ATA interface ■ Memory card readers ■ Legacy conversion devices ■ Home PNA ■ Wireless LAN ■ MP3 players ■ Networking The Reference Designs section of the cypress website provides additional tools for typical USB applications. Each reference design comes complete with firmware source and object code, schematics, and documentation. Please visit http://www.cypress.com for more information. Functional Overview USB Signaling Speed FX1 operates at one of the three rates defined in the USB Specification Revision 2.0, dated April 27, 2000: Full speed, with a signaling bit rate of 12 Mbps. FX1 has an on-chip oscillator circuit that uses an external 24 MHz (±100 ppm) crystal with the following characteristics: ■ Parallel resonant ■ Fundamental mode ■ 500 W drive level ■ 12 pF (5% tolerance) load capacitors. An on-chip PLL multiplies the 24 MHz oscillator up to 480 MHz, as required by the transceiver/PHY, and the internal counters divide it down for use as the 8051 clock. The default 8051 clock frequency is 12 MHz. The clock frequency of the 8051 is dynamically changed by the 8051 through the CPUCS register. The CLKOUT pin, which is three-stated and inverted using the internal control bits, outputs the 50% duty cycle 8051 clock at the selected 8051 clock frequency which is 48, 24, or 12 MHz. USARTS FX1 contains two standard 8051 USARTs, addressed by Special Function Register (SFR) bits. The USART interface pins are available on separate I/O pins, and are not multiplexed with port pins. UART0 and UART1 can operate using an internal clock at 230 KBaud with no more than 1% baud rate error. 230 KBaud operation is achieved by an internally derived clock source that generates overflow pulses at the appropriate time. The internal clock adjusts for the 8051 clock rate (48, 24, 12 MHz) such that it always presents the correct frequency for 230-KBaud operation.[1] Special Function Registers Certain 8051 SFR addresses are populated to provide fast access to critical FX1 functions. These SFR additions are shown in Table 1 on page 5. Bold type indicates non-standard, enhanced 8051 registers. The two SFR rows that end with ‘0’ and ‘8’ contain bit addressable registers. The four I/O ports A–D use the SFR addresses used in the standard 8051 for ports 0–3, which are not implemented in the FX1. Because of the faster and more efficient SFR addressing, the FX1 I/O ports are not addressable in the external RAM space (using the MOVX instruction). Note 1. 115-KBaud operation is also possible by programming the 8051 SMOD0 or SMOD1 bits to a ‘1’ for UART0 and UART1, respectively. Document Number: 38-08039 Rev. *L Page 4 of 74 CY7C64713 Figure 1.

Alternatively, it boot-loads the EEPROM contents into an internal RAM (0xC2). If no EEPROM is detected, FX1 enumerates using internally stored descriptors. The default ID values for FX1 are VID/PID/DID (0x04B4, 0x6473, 0xAxxx where xxx=Chip revision).[2] Buses Table 2.

Document Number: 38-08039 Rev. *L Page 5 of 74 CY7C64713 ReNumeration™ USB-Interrupt Autovectors Because the FX1’s configuration is soft, one chip can take on the identities of multiple distinct USB devices. The main USB interrupt is shared by 27 interrupt sources. The FX1 provides a second level of interrupt vectoring, called Autovectoring, to save code and processing time that is normally required to identify the individual USB interrupt source. When a USB interrupt is asserted, the FX1 pushes the program counter on to its stack and then jumps to address 0x0043, where it expects to find a “jump” instruction to the USB Interrupt service routine. When first plugged into the USB, the FX1 enumerates automatically and downloads firmware and the USB descriptor tables over the USB cable. Next, the FX1 enumerates again, this time as a device defined by the downloaded information. This patented two step process, called ReNumeration, happens instantly when the device is plugged in, with no indication that the initial download step has occurred. Two control bits in the USBCS (USB Control and Status) register control the ReNumeration process: DISCON and RENUM. To simulate a USB disconnect, the firmware sets DISCON to 1. To reconnect, the firmware clears DISCON to 0. Before reconnecting, the firmware sets or clears the RENUM bit to indicate if the firmware or the Default USB Device handles device requests over endpoint zero: ■ RENUM = 0, the Default USB Device handles device requests ■ RENUM = 1, the firmware handles device requests Bus-powered Applications The FX1 fully supports bus powered designs by enumerating with less than 100 mA as required by the USB specification. Interrupt System INT2 Interrupt Request and Enable Registers FX1 implements an autovector feature for INT2 and INT4. There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors. See EZ-USB Technical Reference Manual (TRM) for more details. The FX1 jump instruction is encoded as shown in Table 3. If Autovectoring is enabled (AV2EN = 1 in the INTSETUP register), the FX1 substitutes its INT2VEC byte. Therefore, if the high byte (“page”) of a jump table address is preloaded at location 0x0044, the automatically inserted INT2VEC byte at 0x0045 directs the jump to the correct address out of the 27 addresses within the page. FIFO/GPIF Interrupt (INT4) Just as the USB Interrupt is shared among 27 individual USB-interrupt sources, the FIFO/GPIF interrupt is shared among 14 individual FIFO/GPIF sources. The FIFO/GPIF Interrupt, such as the USB Interrupt, can employ autovectoring. Table 4 on page 7 shows the priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources. FIFO/GPIF Interrupt (INT4) Just as the USB Interrupt is shared among 27 individual USB-interrupt sources, the FIFO/GPIF interrupt is shared among 14 individual FIFO/GPIF sources. The FIFO/GPIF Interrupt, such as the USB Interrupt, can employ autovectoring. Table 4 on page 7 shows the priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources. Table 3.

Therefore, if the high byte (“page”) of a jump-table address is preloaded at location 0x0054, the automatically inserted INT4VEC byte at 0x0055 directs the jump to the correct address out of the 14 addresses within the page. When the ISR occurs, the FX1 pushes the program counter onto its stack and then jumps to address 0x0053, where it expects to find a “jump” instruction to the ISR Interrupt service routine. Note 3. Errata: In Slave FIFO Asynchronous Word Wide mode, if a single word data is transferred from the USB host to EP2, configured as OUT Endpoint (EP) in the first transaction, then the Empty flag behaves incorrectly. This does not happen if the data size is more than one word in the first transaction. For more information, see the “Errata” on page 71. Document Number: 38-08039 Rev. *L Page 7 of 74 CY7C64713 Reset and Wakeup Reset Pin The input pin, RESET#, resets the FX1 when asserted. This pin has hysteresis and is active LOW. When a crystal is used with the CY7C64713, the reset period must allow for the stabilization of the crystal and the PLL. This reset period must be approximately 5 ms after VCC has reached 3.0 Volts. If the crystal input pin is driven by a clock signal the internal PLL stabilizes in 200 s after VCC has reached 3.0 V[4]. Figure 2 on page 8 shows a power on reset condition and a reset applied during operation. A power on reset is defined as the time a reset is asserted when power is being applied to the circuit. A powered reset is defined to be when the FX1 has been previously powered on and operating and the RESET# pin is asserted. Cypress provides an application note which describes and recommends power on reset implementation and is found on the Cypress web site. While the application note discusses the FX2, the information provided applies also to the FX1.

This stops the oscillator and PLL. When WAKEUP is asserted by external logic, the oscillator restarts, after the PLL stabilizes, and then the 8051 receives a The FX1 exits the power down (USB suspend) state using one of the following methods: ■ USB bus activity (if D+/D– lines are left floating, noise on these lines may indicate activity to the FX1 and initiate a wakeup). ■ External logic asserts the WAKEUP pin. ■ External logic asserts the PA3/WU2 pin. The second wakeup pin, WU2, can also be configured as a general purpose I/O pin. This allows a simple external R-C network to be used as a periodic wakeup source. Note that WAKEUP is by default active LOW. Note 4. If the external clock is powered at the same time as the CY7C64713 and has a stabilization wait period. It must be added to the 200 s.

The usable size of these buffers depend on the USB transfer mode as described in the section Organization. In operation, some of the eight RAM blocks fill or empty from the SIE, while the others are connected to the I/O transfer logic. The transfer logic takes two forms: the GPIF for internally generated control signals or the slave FIFO interface for externally controlled transfers. Page 11 of 74 CY7C64713 Figure 6.

The 8051/SIE can switch any of the RAM blocks between two domains: the USB (SIE) domain and the 8051-I/O Unit domain. This switching is done instantaneously, giving essentially zero transfer time between “USB FIFOS” and “Slave FIFOS”. While they are physically the same memory, no bytes are actually transferred between buffers. At any time, some RAM blocks fill or empty with USB data under SIE control, while other RAM blocks are available to the 8051 and the I/O control unit. The RAM blocks operate as a single-port in the USB domain, and dual port in the 8051-I/O domain. The blocks are configured as single, double, triple, or quad buffered. The I/O control unit implements either an internal master (M for master) or external master (S for Slave) interface. In Master (M) mode, the GPIF internally controls FIFOADR[1..0] to select a FIFO. The RDY pins (two in the 56-pin package, six in the 100-pin and 128-pin packages) are used as flag inputs from an external FIFO or other logic if desired. The GPIF is run from either an internally derived clock or an externally supplied clock (IFCLK), at a rate that transfers data up to 96 Megabytes/s (48 MHz IFCLK with 16-bit interface). In Slave (S) mode, the FX1 accepts either an internally derived clock or an externally supplied clock (IFCLK with a maximum frequency of 48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals from external logic. When using an external IFCLK, the external clock must be present before switching to the external clock with the IFCLKSRC bit. Each endpoint can individually be selected for byte or word operation by an internal configuration bit, and a Slave FIFO Output Enable signal SLOE enables data of the selected width. External logic must ensure that the output enable signal is inactive when writing data to a slave FIFO. The slave interface can also operate asynchronously, where the SLRD and SLWR signals act directly EP6 64 64 EP6 64 1023 64 EP8 EP8 Master/Slave Control Signals Document Number: 38-08039 Rev. *L 1023 1023 1023 64 EP8 64 1023 1023 64 EP4 EP6 1023 EP2 EP2 64 1023 6 64 64 64 64 7 8 1023 9 1023 1023 1023 EP8 64 64 64 64 10 1023 11 1023 12 as strobes, rather than a clock qualifier as in the synchronous mode. The signals SLRD, SLWR, SLOE, and PKTEND are gated by the signal SLCS#. GPIF and FIFO Clock Rates An 8051 register bit selects one of two frequencies for the internally supplied interface clock: 30 MHz and 48 MHz. Alternatively, an externally supplied clock of 5 to 48 MHz feeding the IFCLK pin is used as the interface clock. IFCLK is configured to function as an output clock when the GPIF and FIFOs are internally clocked. An output enable bit in the IFCONFIG register turns this clock output off, if desired. Another bit within the IFCONFIG register inverts the IFCLK signal whether internally or externally sourced. GPIF The GPIF is a flexible 8 or 16-bit parallel interface driven by a user programmable finite state machine. It allows the CY7C64713 to perform local bus mastering, and can implement a wide variety of protocols such as ATA interface, printer parallel port, and Utopia. The GPIF has six programmable control outputs (CTL), nine address outputs (GPIFADRx), and six general purpose Ready inputs (RDY). The data bus width is 8 or 16 bits. Each GPIF vector defines the state of the control outputs, and determines what state a Ready input (or multiple inputs) must be before proceeding. The GPIF vector is programmed to advance a FIFO to the next data value, advance an address, and so on. A sequence of the GPIF vectors create a single waveform that executes to perform the data move between the FX1 and the external device. Six Control OUT Signals The 100-pin and 128-pin packages bring out all six Control Output pins (CTL0–CTL5). The 8051 programs the GPIF unit to define the CTL waveforms. The 56-pin package brings out three Page 12 of 74 CY7C64713 of these signals: CTL0–CTL2. CTLx waveform edges are programmed to make transitions as fast as once per clock (20.8 ns using a 48 MHz clock). Six Ready IN Signals The 100-pin and 128-pin packages bring out all six Ready inputs (RDY0–RDY5). The 8051 programs the GPIF unit to test the RDY pins for GPIF branching. The 56 pin package brings out two of these signals, RDY0–1. Nine GPIF Address OUT Signals Nine GPIF address lines are available in the 100-pin and 128-pin packages: GPIFADR[8..0]. The GPIF address lines allow indexing through up to a 512 byte block of RAM. If more address lines are needed, I/O port pins are used. Long Transfer Mode In Master mode, the 8051 appropriately sets the GPIF transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or GPIFTCB0) for unattended transfers of up to 232 transactions. The GPIF automatically throttles data flow to prevent under or overflow until the full number of requested transactions are complete. The GPIF decrements the value in these registers to represent the current status of the transaction. ECC Generation The EZ-USB FX1 can calculate ECCs (Error Correcting Codes) on data that pass across its GPIF or Slave FIFO interfaces. There are two ECC configurations: Two ECCs, each calculated over 256 bytes (SmartMedia™ Standard); and one ECC calculated over 512 bytes. The ECC can correct any one-bit error or detect any two-bit error. Note To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation. ECC Implementation The two ECC configurations are selected by the ECCM bit: 0.0.0.1 ECCM = 0 Two 3-byte ECCs, each calculated over a 256-byte block of data. This configuration conforms to the SmartMedia Standard. Write any value to ECCRESET, then pass data across the GPIF or Slave FIFO interface. The ECC for the first 256 bytes of data is calculated and stored in ECC1. The ECC for the next 256 bytes is stored in ECC2. After the second ECC is calculated, the values in the ECCx registers do not change until the ECCRESET is written again, even if more data is subsequently passed across the interface. 0.0.0.2 ECCM = 1 One 3-byte ECC calculated over a 512-byte block of data. Write any value to ECCRESET, then pass data across the GPIF or Slave FIFO interface. The ECC for the first 512 bytes of data is calculated and stored in ECC1; ECC2 is not used. After the ECC is calculated, the value in ECC1 does not change until the ECCRESET is written again, even if more data is subsequently passed across the interface USB Uploads and Downloads The core has the ability to directly edit the data contents of the internal 16 KByte RAM and of the internal 512 byte scratch pad RAM via a vendor specific command. This capability is normally used when ‘soft’ downloading user code and is available only to and from the internal RAM, only when the 8051 is held in reset. The available RAM spaces are 16 KBytes from 0x0000–0x3FFF (code/data) and 512 bytes from 0xE000–0xE1FF (scratch pad data RAM).[5] Autopointer Access FX1 provides two identical autopointers. They are similar to the internal 8051 data pointers, but with an additional feature: they can optionally increment after every memory access. This capability is available to and from both internal and external RAM. The autopointers are available in external FX1 registers, under the control of a mode bit (AUTOPTRSETUP.0). Using the external FX1 autopointer access (at 0xE67B–0xE67C) allows the autopointer to access all RAM, internal and external, to the part. Also, the autopointers can point to any FX1 register or endpoint buffer space. When autopointer access to external memory is enabled, the location 0xE67B and 0xE67C in XDATA and the code space cannot be used. I2C Controller FX1 has one I2C port that is driven by two internal controllers: one that automatically operates at boot time to load VID/PID/DID and configuration information; and another that the 8051, once running, uses to control external I2C devices. The I2C port operates in master mode only. I2C Port Pins The I2C pins SCL and SDA must have external 2.2 k pull up resistors even if no EEPROM is connected to the FX1. External EEPROM device address pins must be configured properly. See Table 7 for configuring the device address pins. Table 7.

After the data is downloaded from the host, a ‘loader’ executes from the internal RAM to transfer downloaded data to the external memory. 6. This EEPROM has no address pins. Document Number: 38-08039 Rev. *L Page 13 of 74 CY7C64713 I2C Interface Boot Load Access I2 At power on reset the C interface boot loader loads the VID/PID/DID configuration bytes and up to 16 KBytes of program/data. The available RAM spaces are 16 KBytes from 0x0000–0x3FFF and 512 bytes from 0xE000–0xE1FF. The 8051 is in reset. I2C interface boot loads only occur after power on reset. I2C Interface General Purpose Access The 8051 can control peripherals connected to the I2C bus using the I2CTL and I2DAT registers. FX1 provides I2C master control only, because it is never an I2C slave. Compatible with Previous Generation EZ-USB FX2 The EZ-USB FX1 is fit, form, and function upgradable to the EZ-USB FX2LP. This makes for an easy transition for designers wanting to upgrade their systems from full speed to high speed designs. The pinout and package selection are identical, and all firmware developed for the FX1 function in the FX2LP with proper addition of high speed descriptors and speed switching code. Pin Assignments Figure 7 on page 15 identifies all signals for the three package types. The following pages illustrate the individual pin diagrams, Document Number: 38-08039 Rev. *L plus a combination diagram showing which of the full set of signals are available in the 128, 100, and 56-pin packages. The signals on the left edge of the 56-pin package in Figure 7 on page 15 are common to all versions in the FX1 family. Three modes are available in all package versions: Port, GPIF master, and Slave FIFO. These modes define the signals on the right edge of the diagram. The 8051 selects the interface mode using the IFCONFIG[1:0] register bits. Port mode is the power on default configuration. The 100-pin package adds functionality to the 56-pin package by adding these pins: ■ PORTC or alternate GPIFADR[7:0] address signals ■ PORTE or alternate GPIFADR[8] address signal and seven additional 8051 signals ■ Three GPIF Control signals ■ Four GPIF Ready signals ■ Nine 8051 signals (two USARTs, three timer inputs, INT4,and INT5#) ■ BKPT, RD#, WR#. The 128-pin package adds the 8051 address and data buses plus control signals. Note that two of the required signals, RD# and WR#, are present in the 100-pin version. In the 100-pin and 128-pin versions, an 8051 control bit is set to pulse the RD# and WR# pins when the 8051 reads from and writes to the PORTC. Page 14 of 74 CY7C64713 Figure 7.

This pin goes active (HIGH) when the 8051 address bus matches the BPADDRH/L registers and breakpoints are enabled in the BREAKPT register (BPEN = 1). If the BPPULSE bit in the BREAKPT register is HIGH, this signal pulses HIGH for eight 12-/24-/48 MHz clocks. If the BPPULSE bit is LOW, the signal remains HIGH until the 8051 clears the BREAK bit (by writing ‘1’ to it) in the BREAKPT register. RESET# Input N/A Active LOW Reset. Resets the entire chip. See the section Reset and Wakeup on page 8 for more details. EA Input N/A External Access. This pin determines where the 8051 fetches code between addresses 0x0000 and 0x3FFF. If EA = 0 the 8051 fetches this code from its internal RAM. IF EA = 1 the 8051 fetches this code from external memory. XTALIN Input N/A Crystal Input. Connect this signal to a 24 MHz parallel-resonant, fundamental mode crystal and load capacitor to GND. It is also correct to drive the XTALIN with an external 24 MHz square wave derived from another clock source. When driving from an external source, the driving signal must be a 3.3 V square wave.

Document Number: 38-08039 Rev. *L Page 50 of 74 CY7C64713 PORTC Strobe Feature Timings The RD# and WR# are present in the 100 pin version and the 128 pin package. In these 100 pin and 128 pin versions, an 8051 control bit is set to pulse the RD# and WR# pins when the 8051 reads from or writes to the PORTC. This feature is enabled by setting the PORTCSTB bit in CPUCS register. The RD# and WR# strobes are asserted for two CLKOUT cycles when the PORTC is accessed. The WR# strobe is asserted two clock cycles after the PORTC is updated and is active for two clock cycles after that as shown in Figure 16. As for read, the value of the PORTC three clock cycles before the assertion of RD# is the value that the 8051 reads in. The RD# is pulsed for 2 clock cycles after 3 clock cycles from the point when the 8051 has performed a read function on PORTC. In this feature the RD# signal prompts the external logic to prepare the next data byte. Nothing gets sampled internally on assertion of the RD# signal itself. It is just a “prefetch” type signal to get the next data byte prepared. Therefore, using it meets the set up time to the next read. The purpose of this pulsing of RD# is to let the external peripheral know that the 8051 is done reading PORTC and that the data was latched into the PORTC three CLKOUT cycles prior to asserting the RD# signal. After the RD# is pulsed the external logic may update the data on PORTC. The timing diagram of the read and write strobing function on accessing PORTC follows. Refer to Figure 13 on page 49 and Figure 14 on page 50 for details on propagation delay of RD# and WR# signals. Figure 16.

PKTEND is asserted with the last data value clocked into the FIFOs or thereafter. The only consideration is that the set up time tSPE and the hold time tPEH for PKTEND must be met. Although there are no specific timing requirements for asserting PKTEND in relation to SLWR, there exists a specific case condition that needs attention. When using the PKTEND to commit a one byte or word packet, an additional timing requirement must be met when the FIFO is configured to operate in auto mode and it is necessary to send two packets back to back: ■ A full packet (defined as the number of bytes in the FIFO meeting the level set in the AUTOINLEN register) committed automatically followed by ■ A short one byte or word packet committed manually using the PKTEND pin. In this particular scenario, the developer must assert the PKTEND at least one clock cycle after the rising edge that caused the last byte or word to be clocked into the previous auto committed packet. Figure 24 shows this scenario. X is the value the AUTOINLEN register is set to when the IN endpoint is configured to be in auto mode. Figure 24 shows a scenario where two packets are being committed. The first packet is committed automatically when the number of bytes in the FIFO reaches X (value set in AUTOINLEN register) and the second one byte or word short packet being committed manually using PKTEND. Note that there is at least one IFCLK cycle timing between asserting PKTEND and clocking of the last byte of the previous packet (causing the packet to be committed automatically). Failing to adhere to this timing results in the FX2 failing to send the one byte or word short packet. Figure 24.

SLOE is an output enable only, whose sole function is to drive the data bus. The data that is driven on the bus is the data that the internal FIFO pointer is currently pointing to. In this example it is the first data value in the FIFO. Note The data is pre-fetched and is driven on the bus when SLOE is asserted.

SLRD must meet the setup time of tSRD (time from asserting the SLRD signal to the rising edge of the IFCLK) and maintain a minimum hold time of tRDH (time from the IFCLK edge to the deassertion of the SLRD signal). If the SLCS signal is used, it must be asserted with SLRD, or before SLRD is asserted (that is, the SLCS and SLRD signals must both be asserted to start a valid read condition). ■ The FIFO pointer is updated on the rising edge of the IFCLK, while SLRD is asserted. This starts the propagation of data from the newly addressed location to the data bus. After a propagation delay of tXFD (measured from the rising edge of IFCLK) the new data value is present. N is the first data value read from the FIFO. To have data on the FIFO data bus, SLOE MUST also be asserted. At t = 0 the FIFO address is stable and the signal SLCS is asserted (SLCS may be tied low in some applications). Note tSFA has a minimum of 25 ns. This means when IFCLK is running at 48 MHz, the FIFO address setup time is more than one IFCLK cycle. IFCLK N+2 SLRD SLOE Figure 30 shows the timing relationship of the SLAVE FIFO signals during a synchronous FIFO read using IFCLK as the synchronizing clock.

Page 60 of 74 CY7C64713 Note For the burst mode, the SLRD and SLOE are left asserted during the entire duration of the read. In the burst read mode, when SLOE is asserted, data indexed by the FIFO pointer is on the data bus. During the first read cycle, on the rising edge of the clock the FIFO pointer is updated and increments to point to address N + 1. For each subsequent rising edge of IFCLK, while the SLRD is asserted, the FIFO pointer is incremented and the next data value is placed on the data bus.

This diagram illustrates a single write followed by burst write of 3 bytes and committing all 4 bytes as a short packet using the PKTEND pin. ■ At t = 0 the FIFO address is stable and the signal SLCS is asserted (SLCS may be tied low in some applications). Note tSFA has a minimum of 25 ns. This means when IFCLK is running at 48 MHz, the FIFO address setup time is more than one IFCLK cycle. ■ At t = 1, the external master or peripheral must output the data value onto the data bus with a minimum set up time of tSFD before the rising edge of IFCLK. ■ At t = 2, SLWR is asserted. The SLWR must meet the setup time of tSWR (time from asserting the SLWR signal to the rising edge of IFCLK) and maintain a minimum hold time of tWRH (time from the IFCLK edge to the deassertion of the SLWR signal). If SLCS signal is used, it must be asserted with SLWR or before SLWR is asserted. (that is the SLCS and SLWR signals must both be asserted to start a valid write condition). ■ While the SLWR is asserted, data is written to the FIFO and on the rising edge of the IFCLK, the FIFO pointer is incremented. Document Number: 38-08039 Rev. *L The FIFO flag is also updated after a delay of tXFLG from the rising edge of the clock. The same sequence of events are also shown for a burst write and are marked with the time indicators of T = 0 through 5. Note For the burst mode, SLWR and SLCS are left asserted for the entire duration of writing all the required data values. In this burst write mode, after the SLWR is asserted, the data on the FIFO data bus is written to the FIFO on every rising edge of IFCLK. The FIFO pointer is updated on each rising edge of IFCLK. In Figure 32, after the four bytes are written to the FIFO, SLWR is deasserted. The short 4-byte packet is committed to the host by asserting the PKTEND signal. There is no specific timing requirement that must be met for asserting the PKTEND signal with regards to asserting the SLWR signal. PKTEND is asserted with the last data value or thereafter. The only consideration is the setup time tSPE and the hold time tPEH must be met. In the scenario of Figure 32, the number of data values committed includes the last value written to the FIFO. In this example, both the data value and the PKTEND signal are clocked on the same rising edge of IFCLK. PKTEND is asserted in subsequent clock cycles. The FIFOADDR lines must be held constant during the PKTEND assertion. Page 61 of 74 CY7C64713 packet committed manually using the PKTEND pin. In this case, the external master must make sure to assert the PKTEND pin at least one clock cycle after the rising edge that caused the last byte or word to be clocked into the previous auto committed packet (the packet with the number of bytes equal to what is set in the AUTOINLEN register). Refer to Table 19 on page 55 for further details on this timing. Although there are no specific timing requirement for asserting PKTEND, there is a specific corner case condition that needs attention while using the PKTEND to commit a one byte or word packet. Additional timing requirements exist when the FIFO is configured to operate in auto mode and it is necessary to send two packets: a full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by a short one byte or word Sequence Diagram of a Single and Burst Asynchronous Read Figure 33.

It shows a single read followed by a burst read. ■ The data that drives after asserting SLRD, is the updated data from the FIFO. This data is valid after a propagation delay of tXFD from the activating edge of SLRD. In Figure 33, data N is the first valid data read from the FIFO. For data to appear on the data bus during the read cycle (that is, SLRD is asserted), SLOE MUST be in an asserted state. SLRD and SLOE can also be tied together. ■ At t = 0 the FIFO address is stable and the SLCS signal is asserted. ■ At t = 1, SLOE is asserted. This results in the data bus being driven. The data that is driven on to the bus is previous data, it data that was in the FIFO from a prior read cycle. The same sequence of events is also shown for a burst read marked with T = 0 through 5. At t = 2, SLRD is asserted. The SLRD must meet the minimum active pulse of tRDpwl and minimum de-active pulse width of tRDpwh. If SLCS is used then, SLCS must be in asserted with SLRD or before SLRD is asserted (that is, the SLCS and SLRD signals must both be asserted to start a valid read condition). Note In burst read mode, during SLOE is assertion, the data bus is in a driven state and outputs the previous data. After the SLRD is asserted, the data from the FIFO is driven on the data bus (SLOE must also be asserted) and then the FIFO pointer is incremented. ■ Document Number: 38-08039 Rev. *L Page 62 of 74 CY7C64713 Sequence Diagram of a Single and Burst Asynchronous Write In the following figure, dashed lines indicate signals with programmable polarity.

If SLCS is used, it must also be asserted (SLCS may be tied low in some applications). ■ At t = 1 SLWR is asserted. SLWR must meet the minimum active pulse of tWRpwl and minimum de-active pulse width of tWRpwh. If the SLCS is used, it must be in asserted with SLWR or before SLWR is asserted. ■ At t = 2, data must be present on the bus tSFD before the deasserting edge of SLWR. ■ At t = 3, deasserting SLWR causes the data to be written from the data bus to the FIFO and then increments the FIFO pointer. The FIFO flag is also updated after tXFLG from the deasserting edge of SLWR. Document Number: 38-08039 Rev. *L The same sequence of events are shown for a burst write and is indicated by the timing marks of T = 0 through 5. Note In the burst write mode, after SLWR is deasserted, the data is written to the FIFO and then the FIFO pointer is incremented to the next byte in the FIFO. The FIFO pointer is post incremented. In Figure 35, after the four bytes are written to the FIFO and SLWR is deasserted, the short 4-byte packet is committed to the host using the PKTEND. The external device must be designed to not assert SLWR and the PKTEND signal at the same time. It must be designed to assert the PKTEND after SLWR is deasserted and has met the minimum deasserted pulse width. The FIFOADDR lines are to be held constant during the PKTEND assertion.

As a result, special attention is required to the heat transfer area below the package to provide a good thermal bond to the circuit board. A Copper (Cu) fill is to be designed into the PCB as a thermal pad under the package. Heat is transferred from the FX1 through the device’s metal paddle on the bottom side of the package. Heat from here, is conducted to the PCB at the thermal pad. It is then conducted from the thermal pad to the PCB inner ground plane by a 5 × 5 array of via. A via is a plated through hole in the PCB with a finished diameter of 13 mil. The QFN’s metal die paddle must be soldered to the PCB’s thermal pad. Solder mask is placed on the board top side over each via to resist solder flow into the via. The mask on the top side also minimizes outgassing during the solder reflow process.

This can be found on Amkor's website http://www.amkor.com. The application note provides detailed information on board mounting guidelines, soldering flow, rework process, and so on. Figure 40 on page 69 displays a cross-sectional area underneath the package. The cross section is of only one via. The solder paste template needs to be designed to allow at least 50% solder coverage. The thickness of the solder paste template must be 5 mil. It is recommended that ‘No Clean’ type 3 solder paste is used for mounting the part. Nitrogen purge is recommended during reflow.

Items [1]. Empty Flag Assertion Part Number Silicon Revision CY7C64713/4 B Fix Status No silicon fix planned currently. Use workaround 1. Empty Flag Assertion ■ Problem Definition When Configured in Slave FIFO Asynchronous Word Wide mode and if only single word data transferred from USB Host to EP2 configured as OUT End Point (EP) in the very first transaction then Empty flag behaves incorrectly. This does not happened if data size is more than a word length in the first transaction. ■ Parameters Affected NA ■ Trigger Condition(S) In Slave FIFO Word Wide Mode, after firmware boot and initialization, EP2 OUT Endpoint empty flag indicates status as Empty. Upon data reception in EP2 it changes to Not-Empty. But if data transferred to EP2 is single word only, then asserting SLRD with FIFOADR pointing to any other Endpoint, changes Not-Empty status to Empty for EP2 even though a word data is there (or it is untouched) in EP2. This is noticed only when the single word is sent as the very first transaction and does not happen if it follows multi-word packet as the first transaction. ■ Scope of Impact External interface does not see data available in EP2 OUT Endpoint and might end up waiting for data to be read. ■ Workaround Any one of the following workaround can be used i.Give out Pulse signal to the SLWR pin, with FIFOADR pins pointing to an Endpoint other than EP2, after firmware initialization and before/after transferring the data to EP2 from Host, or ii.Set length of very first data to EP2 to be more than a word, or iii.Prioritize EP2 read from Master in case of multiple OUT EPs and single word write to EP2, or iv.Write to any IN EP, if any, from Master before reading from other OUT EPs (other than EP2) from Master. ■ Fix Status There is no silicon fix planned for this currently, you can use above workaround.
